Scope

This part of GB 20888 specifies the safety requirements and test methods for the design, structure and use of portable pole-type power pruning saws that use internal combustion engines as power sources to transmit power to cutting parts through drive shafts. Cutting components in this section refer to saw chains and saw blades that reciprocate or rotate. This part proposes ways to eliminate or reduce various hazards arising from the use of internal combustion engine-powered portable pole-powered pruning saws, and specifies the information requirements for safe operation provided by the manufacturer. This section does not propose to eliminate or reduce the electric shock hazards caused by overhead cables that have been warned in the operation manual, because the related safety requirements and test methods still need to be explored and improved. Appendix A lists some of the significant hazards that should reduce the hazards of the program. This section does not address the environmental aspects of pruning saws. This section applies to products produced after its promulgation and implementation.
